Puff-Lon fire lapping ballistic filler is made with optical disk shaped polishing compounds, which makes it difficult to embed into surface you are trying to polish. The polish is impregnated into a lightweight 100% Pure Cellulose that is compressible and has resiliency. It is granulated so it can be handled with the same ease as your gunpowder and has an infinite shelf-life.

The kit contains four grades of polishing compound:

Coarse: Use on new production barrels to smooth out machining marks or barrels with erosion or corrosion.Medium: Use after coarse or on medium smooth barrels.Fine: Use after medium or on smooth barrels.Extra Fine: Use after fine or to achieve a mirror finish inside the bore. Use Puff-Lon "Lubricating Ballistic Filler" to keep it that way.

CAUTION: All loads should be at least 15% below SAAMI maximum recommendations. Crimp your bullet in place. Do not seat bullet touching forcing cone. Lube all bullets that have lube grooves. Disconnect the gas tube on gas-operated automatics if you DO NOT wish to polish the piston assembly. For best Accuracy during lapping process, do not use boat tail bullets. Do not use fast burning smokeless powders such as pistol or shotgun powder when near maximum load in rifle cartridges.

DISCLAIMER: Safe reloading practices are the responsibility of the loader. Unsafe reloading may result in serious injury including death and/or damage to personal property. Puff-Lon and it's agents, distributors and assigns assume no responsibility for injury or damage resulting from the improper use of this product.

Thank you for purchasing Puff-Lon fire lapping ballistic filler kit. Lapping by firing cartridges that have abrasive fillers is a new concept. Every gun will benefit from bore lapping. Cleaning will be easier and accuracy will be improved. The bore lapping process removes only a small amount of steel, therefore it will not remove deep pits but does smooth the edges of them.
